Ever wanted to plug a tape player & a cd player into a mixing console, but didn’t have enough channels? The JIB/R will allow you to sum two stereo sources such as a tape, cd, mini disc, or mp3 player, and combine them into one mono XLR or ¼” output. This allows one channel to be freed up for other important inputs. The JIB/R, also has a phantom block circuit which prevents phantom power going to the input sources. Combines (sums) two stereo CD or tape players into one mono (XLR or ¼ inch) output. Frees mixer channels. Phantom block on the XLR prevents phantom power from reaching CD/Tape players connected to the RCA jacks.
